Log Message:
rk3399 pcie: pay attention to the "bus-scan-delay-ms" property.

our existing pinebookpro DTS, but not the other rk3399 ones, have
this property set to "1000" (it's the same in linux 5.14 DTS.)

as there are already static 100ms + upto 1000ms, count how many
are done, and only delay more to complete one second.

this allows reverting this device-specific change:

   http://mail-index.netbsd.org/source-changes/2021/06/23/msg130402.html

and makes other sorts of storage cards more likely to work as well.

tested on rockpro64.

XXX:  consider moving dts setting into rk3399.dtsi.
